METHOD FOR THERMOCHEMICAL TREATMENT OF BOTTOM-HOLE OIL FORMATION ZONE Russian patent published in 1996 - IPC

Abstract RU 2070283 C1

FIELD: oil producing industry. SUBSTANCE: method for thermochemical treatment of bottom-hole oil formation zone includes injection into formation of acetone, aqueous 30-48% solution of sodium nitrite and 30-35% hydrochloric acid. Volumetric ratio of the reagents is (1.2-2.1):(7.9-10.7): (3.5-21.6). EFFECT: increased depth of treatment due to increased induction period of intraformation exothermic reaction. 1 tbl
